Summary: its manufacturer discontinued and not supported. no accessories available. bought this to feed a gps signal to my vhf dsc radio on my boat, it does not, and no cords are available to connect it.
Summary: I have used my GO2 for several years with great success. The map of the Jourdan River in MS kept me on course and out of alligator swamps. But then it stopped working and would not get a fix on satellites. I called Lowrance for repairs and was told that this unit is "NO LONGER SUPPORTED".
Summary: The Lowrance ifinder g02 receiver is very accurate. It is spot on with a little bounce but accurate. The receiver did come with a broken part where battery is, although it was an easy fix. It is a good item to get for directions. It is the best size, not too big but not too small.
Summary: Gave this unit 5 stars. It was inexpensive,easy to use,accurate to 9 feet,and doesn't eat up batteries like most units. Not as fancy as units with topo maps or as colorful as others but I didn't pay a fortune for mine either. I use mine for fishing and it always gets me back to my favorite spots.
